thanks to everybody who replied publicly or privately to my announcement. yes, I prefer to be corrected privately because otherwise it can interfere with a flow of the thread (btw, articles are the main difficulty. Russian doesn't have it and I put them almost at random).
Fluency? I do not open "Wordplay and fun" 'cos it's far beyond me but I hope I am close to any professional - a lot of professional terms + "everyday talk". I read British newspapers and understand 99.9% of words.

I am glad to be contacted by a translator. I had a pleasure to be helped by ModestGoddess but she announced that she's going to spend less time there. I prefer to see her around!
